Subaru has unveiled the most extensive revision of its Impreza WRC since the model débuted in 2001. The new Scooby will be crucial to Petter Solberg’s hopes of defending his title.


According to the Japanese-based team, the WRC2004 is the result of a 14-month re-design carried out by ex-Ferrari engineer Ed Wood, who focused his efforts on making engine, electronics and bodyshell refinements.


The greater use of finite element analysis has contributed to lighter and tougher suspension links. The bodyshell has a new rollcage and is fitted with plastic side windows and lighter wings. However, Prodrive has decided to make new front wings from aluminium rather than carbonfibre, partly on cost grounds.


Team director David Lapworth said that the WRC2004 would nevertheless be on the 1230-kg weight limit and that ballast will be carried when it competes for the first time on the Corona Rally Mexico in mid-March.


The TAG electronics system first revealed on last October’s San Remo Rally has been combined with a new wiring loom and software developed by STi in Japan and Prodrive. The WRC2004 is the first Subaru rally car to have a single ECU that controls all functions.


The pedal box, rear differential, turbo and cooling system are all new and power, torque are all said to be improved.


“We’re pleased with the performance. It’s a nice step forward. If you draw a line of progress year on year, it’s at least on the line or above the line,” Lapworth said.
